Microstructural evolution of tungsten carbide-cobalt alloys.

The microstructural development and grain coarsening behavior of WC-Co alloys, with and without a VC additive, has been investigated. The primary goal of this study was to determine the mechanism through which VC acts as a grain-growth inhibitor.; The study involved long-time sintering experiments (

Liquid diffusion in aluminum.

The liquid diffusivity of copper solute in aluminum was measured at ranges of 700-800°C. A long capillary method was developed for the creation and testing of liquid diffusion couples, in order to quantify the extent of convective flow in previous studies which utilized a capillary reservoir tec
